Rotor disk

摘要

The invention relates to a rotor disk (1) for inserting into a receiving container (2) for treating polymers, comprising a disk body (3), on the upper face (4) of which mixing and/or comminuting tools (5) can be provided and on the opposite lower face (6) of which a number of conveying ribs (7) extending from the inside out is provided, by means of which conveying ribs polymer particles can be conveyed outward during operation or which conveying ribs exert a force directed outward from the center (8) of the rotor disk (1) on the polymer particles caught by the conveying ribs (7) during operation. According to the invention, the thickness of the disk body (3) is reduced toward the outside.

主权项

1. A rotor disk for installation in a receiving container for the treatment of polymers, comprising:
a disc body configured to provide on an upper face of the disc body at least one era mixing or a comminuting tool and configured to provide on a lower face of the disc body a number of conveying ribs which extend from a center of the disc body toward a circumference of the disc body, wherein said conveying ribs are concavely curved in a rotational or a running direction, further wherein said conveying ribs are configured to at least one of convey polymer particles toward a circumference of the disc body during operation or exert a force directed outward from the center of the rotor disk on the polymer particles caught by the conveying ribs during operation, wherein the thickness of the disk body in an inner section is constant, and starting from a distance from the center of the rotor disk of 60% to 70% of the radius of the disk body is reduced towards the circumference of the disk body, and further wherein the disk body decreases in thickness toward the circumference of the disc body in the same proportion as the conveying ribs increase in height toward the circumference of the disc body such that the overall thickness of the rotor disk is equal and constant over the radius of the disc body.
